SPECIFICATION forming part of Letters Patent No. 780,682, dated January24:, 1905. Application filed September 21, 1903. Serial IIo. 173,953.

To all whom it may concern.-

Be it known that I, JosnPH PosoH, acitizen of the United States ofAmerica, and a resident of St. Paul, in the county of Ramsey and StateofMinnesota, have invented certain new and useful Improvements inaCombined Trap, Filter, and Air-Distributer, of which the following is aspecification.

Fig. 1.

My invention relates to improvements in a combined trap, filter, andair-distributer, and is more particularly adapted for use in connectionwith beer-pump apparatus.

The object of my invention is to provide a system of air-tubes and atrap for filtering the air and collecting and removing the impurities ofthe beverage in the pipes.

A further object is to produce a combined trap, filter, andair-distributor, which is in use cleanly and convenient.

In the accompanying drawings, forming part of this specification, Figure1 is a diagrammatic view of a beer-pump apparatus, showing my combinedtrap, filter, and airdistributer connected thereto. Fig. 2 is a sideelevation. partly in section, of my invention. Fig. 3 is a section ofFig. 2, taken on the line X X; and Fig. 4 is a detail vertical sectionof Fig. 2. p

In the drawings let A represent the combined trap, filter, andair-distributer, which consists of the upper and lowersocket-plates 3and 4: for holding the hollow glass cylinder 5 between them by means ofthe tie-rods 6. These tie-rods pass through the upper socketplate andare threaded at 7 into the lower socket-plate. Washers, such as areindicated at 8 in Fig. 4, may be inserted between the ends of thecylinder and the socket-plates for the purpose of making air-tightjoints and I preventing the cracking of the glass when the plates arefastened. The socket-plate 3 has with the air-tube 11, which projectsdownward through the cap and into the glass cylinder 5. The air-tubeconnects with the nipple 12, which is for the purpose of connecting withthe air-supply tube B, as shown in v The cap is also provided with thethreaded openings 13 and 1. 1 for the outletpipes C and D. The lowersocket-plate 4: is

formed with the downwardly-projecting por-.

tion 15, which terminates in an opening 16, as indicated in Fig. 2, andis threaded at 17 for the purpose. of receiving the cap-screw 18 forclosing the opening. This cap-screw is pro- ;vided with the Garms 19 forconvenience in is placed on the air-tube 11 through the hole 24 andabuts against the shoulder 25 on the air-tube. The portion of theair-tube within the strainer is perforated at 26, and the inclosure 21is filled with suitable filtering material S, which is adapted to filterthe air as it is forced through the air-tube into the cylinder. videdwith a depending rod 27 and thumbscrew 28, by which the inclosure 21 isfastened in the cylinder.

In use the combined trap, filter, and airdistributer is connected with abeer-pump apparatus. This apparatus may be of any ordinary formsuch, forexample, as shown in Fig. 1, which is as follows: The tube B con-.

nects with the the reservoir F and carries the pressure-gage 29. Thepipes C and D connect with the bungs and draft-tubes G and H. Thesebungs and draft-tubes are of ordinary construction and are adapted foruse in connection with the kegs I and J to draw the beverage therefrom.The draft-tubes are connected with the draw-01f faucets K and L by meansof the pipes M and N. The valves 0 are shown interposed in the pipes Mand N, so that either one orthe other, or both, of the kegs may be used.The air-valves P are connected with the pipes O and D for the samepurpose.

Obviously a number of additional kegs may be added to the system, ifdesired.

In operation the air-reservoir may be filled to the desired pressure bymeans of the pump Q. When filled, the valve R is closed and the valves Popened. If it is desired to use The lower end of the air-tube is prothebeverage in both kegs I and J, the valves.

0 are opened and the faucets K and L used to draw off the beverage. Whenthe system is in operation, sediment and impurities in the beverage areforced out of the kegs by effervescence and gradually collect in theair-distributing chamber A. These impurities are visible through theglass cylinder and may be drawn off through the cock 20. Should theamount of sediment become too great for removal through the draw-offcock, the cap 18 may be unscrewed. As the air enters the distributingchamber through the airtube it is purified by the filter. Obviously thisis desirable, for usually the air that is used in connection withthe'system is damp and foul, and the filter overcomes this objection.When the filtering material absorbs and becomes saturated with theimpurities in the distributing-chamber, it may be cleaned by separatingthe parts of the distribute! and filter and the filtering material inthe inclosure 21 renewed.

It is obvious that this invention may be used in connection with otherair or gas apparatus than that described.

Having described my invention, what I claim as new, and desire toprotect by Letters Patent, is

1. Acombined trap and air-distributer, consisting of a cylindricalreceptacle, upper and lower plates in which the ends of said receptacleare soeketed, tie-rods by which said plates are fastened on said ends, aremovable cap on the upper plate having air inlet and outletpassage-ways, a tube depending from said cap and connected with theair-inlet, said tube having a series of perforations, a filtersurrounding said perforations, and means for removably fastening saidfilter to said tube.

2. In combination with beer-pump apparatus, a system of air-tubes havinga combined trap, filter and air-distributer, a receptacle. a removablecap on said receptacle having airoutlets therein, an air-inlet tube onsaid cap and projecting downward in said receptacle, an air-filterconnected with said air-tube in said receptacle, means for detachablysupporting said filter on said tube, and means for emptying saidreceptacle at the lower end thereof, for the purposes specified.

3. A device of the class set forth, consisting of a cylindricalreceptacle 5, upper and lower socket-plates 3 and 4, tie-rods 6 by whichthe cylinder is held between said plates, a removable cap threaded onthe upper socketplate, an air-tube projecting down from said cap andinto the upper end of said receptacle, a nipple 12 on said cap andconnected with said tube, perforations 26 in the projecting end of saidtube, an air-filter E surrounding the perforated end of said tube, a rod27 depending from said tube, a thumb-nut 28 threaded on said red bywhich said filter is fastened on said tube, outlet-openings l3 and 14:in said cap, and a draw-off cock 20 on the lower end of said receptacle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH POSGH.
